Basic Tuning Adjustments 1. The following instructions are for basic fuel tuning. Modes 1,2, & 3 are allowing adjustments to increase and decrease the amount of fuel the engine needs. Modes 4 & 5 are for advanced tuning only. DO NOT change modes 4 & 5 when doing basic tuning! 2. To help understand how these modes work, you can think of them as if you were working with a carburetor. 3. Remember each time you push the MODE button you will be advancing to the next mode. Push the MODE button once and you are now in mode 1, push the MODE button again and you are now in mode 2 and so on. You only need to be concerned with modes 1, 2 & 3 for basic tuning. Modes 4 & 5 are for advanced tuning ONLY. 4. If you need to go back to the settings that were pre programmed when you purchased the controller, just look at the picture in each mode, the colored square represents where the settings were when you purchased the controller. 5. Looking at the controller you will see eight lights with numbers under them, this is what you need to look at when changing settings. The #1 light on the controller represents the leanest setting.

If you are confident about your tuning skills and feel you need to adjust other parameters, see Advanced Tuning. 12 34 56 7 8 Advanced Tuning Adjustments 1. Advance tuning has two modes in which to adjust. They are called mode 4 and mode 5. In basic tuning, you are changing the amount of fuel that the engine receives, but with advance tuning, you will be changing when the fuel will be available. In each mode you can adjust how soon the fuel delivery occurs. 2. Mode 4 yellow light and blue light represent when the fuel delivery is available during partial throttle acceleration. To adjust this setting, push the MODE button four times and then push the plus or minus buttons to adjust fuel as needed. Only the yellow light will be changing.

your Mikuni HSR is fitted with the tuning parts we found to work with the great majority of engine performance modifications. However, the large number of differing exhaust systems and cams available makes it impossible to accommodate all possible combinations with one carburetor set-up. Your HSR will almost certainly run correctly on your engine without exchanging any parts. But, if it doesn’t, you may alter its tuning to suit your engine’s needs by following this guide. Some exhaust system designs strongly interfere with carburetor tuning. For instance, it is very difficult to get smooth and responsive carburetion through the entire rpm range with straight pipes and completely open exhausts. In addition, very small volume, small diameter mufflers are often ‘seen’ by the engine as straight pipes and present the same tuning difficulties. Very long duration cams often cause relatively poor running below about 3,000 rpm, depending upon the individual cam’s intake valve closing point. Such cams cause reverse airflow out the mouth of the carburetor (often called “reversion” or “standoff”) that can be mistaken for a carburetor tuning problem. Harley-Davidson Screamin’ Eagle performance parts are proven and predictable. If you have any doubts about a particular exhaust system, air cleaner or ignition, you may substitute the Harley Screamin’ Eagle parts as a “reality check.” When re-tuning is required, it usually involves small alterations to the idle and/or main system. The following pages supply enough information to make such alterations relatively simple. Please note that there is no point in attempting to tune any carburetor unless the engine is sound and in a good state of tune. If you have any doubts about the general condition of your engine, have it checked by your dealer or an experienced mechanic before attempting to fine-tune your Mikuni.

1. Check the exhaust system. If you can insert a broomstick through the mufflers, you have the equivalent of open drag pipes and auto-tuning will fail. If applicable, read the section about exhaust considerations starting on page 11. 2. Check for updates. This tuning manual is for TCFI III units with revision 3.3 or higher firmware. Before proceeding, check our website at www.daytona- twintec.com for available updates for the TCFI firmware, accompanying PC based software, and documentation. 3. Tech support. If you have questions or encounter problems at any point during the installation process, please contact our tech support at 386- 304-0700. 4. USB interface. Read the USB interface instructions starting on page 17, install the USB drivers and configure the COM port. 5. PC Link software used for setup and engine tuning. Read the PC Link TCFI III instructions starting on page 19 and install the software. 6. Data logging software. Read the TCFI III Log instructions starting on page 34 and install the software. 7. TCFI Controller. Read the TCFI installation instructions starting on page 41 and install the TCFI unit. Make sure you install the green PC link jumper wire. 8. WEGO wide-band exhaust gas oxygen sensor interface. Read the WEGO installation instructions starting on page 42, install the WEGO unit and perform the free air calibration described on page 43. 9. Connect the USB interface cable between the TCFI unit and your PC. 10. Start the PC Link TCFI III software, use the Open File command, and open the appropriate setup file. Setup data files are provided in the program folder for typical engine applications. Refer to Table 3 on page 16 for details. Additional setup guidelines for aftermarket throttle bodies and larger displacement engines are given on page 9. 11. Use the Edit Basic Parameters command. Make any required changes such as estimated rear wheel horsepower, injector flow rating (refer to Table 1 on page 9), and RPM limit. You must set the vehicle speed sensor (VSS) frequency for your model. This affects speedometer/odometer scaling, idle RPM control, and turn signal

1. The Stage IV controller can be mounted in numerous places. Placement depends on personal preferences. Only mount in locations where no damage may occur from sharp or hot objects. 4. Start the UTV and in approximately four seconds the lights on the Stage IV controller will be visible. With a proper install, you should see lights going from side to side on the controller. This will last approximately eight seconds and then will stop. After lights have stopped going side to side, you will notice a great light on the left side of the controller. When you rev the motor, lights will increase across the controller and even change colors. 5. Double check all fasteners and connections. 7. The Stage IV controller has been programmed for ultimate performance when using Trinity Racing’s Stage IV exhaust system and Powerflow intake system on an otherwise stock engine. Different products, modifications, or other conditions may require additional adjustments. Please refer to Basic Tuning Adjustments and all final fuel adjustments are the customer’s responsibility. 8. You are now ready to ride! Enjoy your new Stage IV fuel management controller!

This manual is intended as a guide for users of Mikuni carburetors who want to learn the adjusting method to the best performance from our products. In motorcycles, special tuning of the engine is now considereda routine practice. The arrows that appear in the drawings in this text show the direction in which air, fuel and an air-fuel mixture flows, respectively. ¢JAir Fuel “Mixture Mounting angle fore and aft inclination of the carb should not exceed approx Function of a carburetor The function of a carburetor is to produce combustible air-fuel mixture, by breaking fuel into tiny particles (in the form of vapor) and by mixing the fuel with air in a proper ratio, and to deliver the mixture to the engine. A proper ratio (mixture ratio or air-fuel ratio) means an ideal air-fuel mixture that can burn without leaving an excess of fuel or air, Whether the proper mixture ratio is maintained or not holds the key to the efficient engine operation, 2. Air-fuel mixture required by the engine (Fig. 1) The ratio of a mixture of fuel and air is called the mixture ratio or the air-fuel ratio and is generally expressed by the weight proportion. Theoretically, the amount of air required for complete combustion of 1 gram of fuel under normal conditions is
